Rudy Giuliani and his wife, Judith, are divorcing after 15 years of marriage, the former New York mayor confirmed first to Page Six.

Giuliani, who married Judith in 2003, said, “It is with great sadness I can confirm that Judith and I are divorcing. We hope to do this as amicably as possible, and hope that people will respect the privacy of our children at this time.”

Judith on Wednesday filed a contested divorce proceeding in Manhattan Supreme Court, which indicates she’s readying for a fight over their marital assets, which include property in Manhattan and Palm Beach, Fla.

Rudy, 73, and Judith, 63, both have adult children from previous marriages.

He has Andrew and Caroline with his second wife, Donna Hanover, who had accused him of cheating after he’d famously announced they were separating at a 2000 press conference.

They divorced in 2002.

Judith has a daughter, Whitney, from her marriage to Bruce Nathan, which ended in 1992.

It was the third marriage for each.

Confirming Judith had filed for divorce, Rudy added to Page Six, “In these divorce situations, you cannot place blame, it is 50/50, there are problems on both sides. We will have to divide our properties in New York and Palm Beach.”

The divorce is a shock to society friends after the Giulianis were seen amicably dining in Palm Beach together a few weeks ago. And on Monday, they dined at Manhattan power spot Fresco by Scotto, where witnesses said they were “smiling and laughing it up” with Caroline.

But other friends said there were serious problems.

One told us, “Sometimes, you don’t know what is crumbling inside a marriage until it hits. Behind closed doors, they’ve been fighting a lot.”
